DISPLAY DEVICE.

SPECIFICATION forming part of Letters Patent No. 766,627, dated. August 2, 1904.

Application filed March 5, 1904. Serial No. 196,641. (No model.)

To all whmn it Hm/y concern:

Be it known that I, LEON A. DE KnRNAY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Display Devices, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved display device for jewelry, and particularly for jewelry in which a jewel or stone or other ornament is resiliently mounted and whereby the jewel, stone, or other ornament will be kept in a constant state of vibration; and with this and other objects in view the invention consists in a device of the class specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a front view of my improved display device; Fig. 2, a sectional side view thereof, and Fig. 3 a sectional inside view of a part of the construction which I employ.

In the practice of my invention I provide a base a, on which is vibratorily mounted an ordinary pincushion or similar device I). The connection between the base a and the cushion 7) is preferably made by means of a standard connected with the bottom of said cushion and passing down through an opening 7) in the top of the base a and pivoted below said opening, as shown at 7/".

In one side of the base a is passed an ordinary clock 0, the dial of which shows through the side of said base, as shown in Fig. 1, and the inner end of the shaft with which the minute-hand of the clock is connected is projected and provided with a gearwheel (7, which meshes with a pinion 3, supported just below the top of the base a and the shaft of which is provided with a cam-wheel or similar device f, which projects through an opening f in the top of the base a. The base a is also provided opposite the wheel f with a spring 9, which is secured thereto and the free end of which presses on the bottom of the cushion 7), and the spring 7 serves to hold the opposite side of the cushion 7) or the bottom thereof always on the wheel f. The wheel f is of irregular form and in the form of construction shown is provided with a plurality of cam projections f and corresponding depressions f, and as said wheel is slowly revolved by the clock mechanism the cushion 7) is constantly given avibratory motion on its pivotal sup port 5*, said motion being produced by the spring g operating in connection with the wheel f.

As hereinbefore stated, the cushion 7) is intended as a support or holder for jewelry provided with vibratory or resilient mountings whereby a stone or other ornament is kept in a constant state of vibration and an example of which is shown and described in United States Letters Patent to Boismaure, No. 64:5,909, granted March 20, 1900, which shows and describes a stick or scarf pin provided with a resiliently or vibratorily mounted jewel or stone, and it will be apparent that when such a pinor similar device is stuck into or supported by the cushion 7) the jewel or stone will be kept in a constant state of vibration, the movement of the cushion occasioned by the wheel 1" and the spring 1 being sufficient to accomplish this result.

In the form of construction shown I employ a clock for the purpose of giving the desired motion to the cushion 7), and in this form of construction my improvement consists in the combination, with a clock or clock-casing, of the cushion 7), supported in a manner described and vibrated by the clock mechanism and the spring g; but it will be apparent that any suitable spring mechanism may be substituted for the clock 0, and such mechanism may be located in the cushion, if desired, and other changes in and modifications of the construction described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

1. An article of the class described, com- 5 prising a base, and a cushion pivotally supported thereover, and means for agitating or vibrating said cushion, substantially as shown and described.

2. A device of the class described, compris- IO ing a base, a cushion pivotally supported ,thereover, and means for agitating or vibrating said cushion comprising a spring mechanism located in one of said parts and adapted to operate in connection with the other, sub- 5 stantially as shown and described.

3. A device of the class described, compris- LEON A. DE KERNAY.
